.10 Claims. (Cl. 2'l417) This invention relates to phonographs, and more particularly to improvements in signalling means for phonographs of the commercial type.

Although commercial phonographs, or dictating machines, are intended to be used almost exclusively for recording purposes, they are commonly arranged so that they may be also used for reproducing purposes-so as for example to permit the operator, while in the process of recording, to listen back on (i. e., to reproduce) previously recorded portions, as desired. When, after such a previously recorded portion has been reproduced, the operator desires to resume recording, he may forget to recondition the machine for recording and proceed to dictate into the machine while it is still in a condition for reproducing, or perhaps even in an inoperative condition. In order to avoid such possible misoperation of the machine, the operators of dictating machines have found it to be particularly useful to have some form of signalling means, other than that naturally provided by the visual relationship of operative parts of the machine, for indicating in some positive manner the condition of the machine, these signalling means being commonly in the form of sound or light signals.

It is an object of this invention to provide, in phonographs, improved means for controlling the operation of such signalling means.

It is another object to provide a positive and complete control of such signalling means by the use of a single switch.

It is another object to provide means, comprising a single switch, for controlling the operation of a signal so that the signal will indicate predetermined conditions of the phonograph, and so that the signal will be positively rendered inoperative when the operation of the phonograph is stopped.-

It is another object to provide means of improved form and operation for intermittently operating a signal while the phonograph is in a predetermined condition and for rendering the signal inoperative while the phonograph is out of operation.

Another object is to control a signalling means for phonographs by the use of an inertia-operated switch which is both statically and dynamically controlled.

Other objects lie in the provision of a control for such signalling means which is highly simplified in form, long-lived, and in simple relationship with other components of the machine.

Still other and allied objects will more fully appear from the following description and the appended claims.

In the description of my invention reference is had to the accompanying drawings, of which:

Reference being had particularly to Figs. 1 and 4, there will be seen a typical form of commercial phonograph comprising a base plate I, provided with an intermediate standard 2 and with similar left and right standards of which the lefthand one appears as 3. J ournalled into the intermediate standard 2 is a shaft 4 carrying a mandrel 4 onto which there may be removably mounted a cylindrical record R. The record R may be rotated as by a motor M, diagrammatically represented in Fig. 7, which may be suitably located beneath the rearward portion of the base plate I and coupled to a pulley5, as by a suitable belt passing through an opening 6 provided in the base plate I. The pulley 5 is rotatably supported by the standard 3 axially in line with the mandrel shaft 4', and is adapted to be coupled, at will, with the mandrel shaft by means of a clutch 9. This clutch comprises a toothed clutch member I on the pulley 5 and another toothed clutch member 8 which is splined on the shaft 4' so that it may be moved into and out of engagement with the clutch member I for operating the clutch 9. Such movement of member 8 may be effected by a vertical clutch lever HI pivoted on a bracket l0 secured to the standard 2 and carrying 'at its upper end a pin II which engages an annular groove- I! on the clutch member 8. The lower end of the lever 9 may project downwardly through the opening 6 and pivotally connect, as bya link l3, with a suitable actuating mechanism for operating the clutch. A form of clutch mechanism which may, for example, be suitably employed is disclosed in U. S. Patent No. 1,380,- 486 to S. G. Langley. This form of mechanism, which is hereinafter described, is diagrammatically represented in Fig. "I as l4.

Supported by the aforementioned left and right standards, and parallel with axis of the mandrel 4, are front and back carriage rods l and I5 on which a carriage [1- is mounted for movement therealong. The rearward portion of the carriage is of a shell form in which there is provided a feed nut l8 secured to a bracket l9 having left and right turned-over cars 20 pivoted on a cross rod 2| supported by the carriage.

The bracket I9 is biased in a clockwise direction, as by a suitable spring 22 connected between an upwardly extending arm 23 on the bracket and a cross rod 24 on the carriage, so as to urge the feed nut.

l8 into engagement with a feed screw 25 rotatably supported by the left and right standards. Such engagement may, however, be controlled at will by means of a forwardly extending control lever 26 mounted on the right side of the carriage and coupled by a link 21 to the right leg of a U- shaped member 28 slidably mounted within the carriage on the rod [5. This member carries between its legs a cross rod 29 which engages a cam face 30 provided on a turned. over and forwardly extending arm 3| of. the bracket I9. When the control lever 26 is in an inoperative position, as shown in Fig. 4, the feed nut I8 is held by the cross rod 29 out of engagement with the feed screw 25; whereas when the control lever is moved in either upward or downward positions with respect to its inoperative position, the rod 29 is moved out of contact with the cam face 30 to render the feed nut free to move, in response to its biasing into engagement with the feed screw. At the leftward end of the feed screw 25 there is provided a gear wheel 32 coupled by a gear system 33 to the mandrel shaft 4' so that rotation of the mandrel may effect rotation of the feed screw, and thereby steadily move the carriage along the mandrel whenever the feed nut I8 is in engagement with the feed screw.

The carriage I1 is extended forwardly above the record R, and is there provided with an aperture in which is retained a sound translating device 34. This device may be provided with recording and reproducing styli 35 and 36 each movable into engagement with the record R. The movement of the styli may be controlled by the lever 26 through lifting fingers 31 and lugs 38, the fingers being pivoted on the rod 2| and respectively provided with suitable cam faces 39 which are maintained in engagement with the cross rod 29, as by springs 40 which urge the lifting arms upwardly against the rod 29. This control of the translating device by the lever 26 is such that when the control lever 26 is in a downward or recording position the feed nut is in engagement with the feed screw and the recording stylus 35 is in operative engagement with the record to effect a recording adjustment of the translating device; that when the lever is ina neutral or inoperative position (as illustrated) the feed nut is disengaged and both styli are out of engagement with the record to effect an inoperative adjustment of the translating device; and that when the lever is in an upward or reproducing position the feed nut is engaged and the reproducing stylus 36 is in operative engagement with the record to eflect a reproducing adjustment of the translating device.

For conducting sound to the translating device 34 during recording and away from the device during reproducing, there may be provided a flexible speaking tube 4|; this tube is commonly swivellingly coupled to the translating device and provided with a handpiece 42 at its outer end which is usable as a mouthpiece during recording or as an earpiece during reproducing. On the handpiece 42, there may be provided a means for controlling the operation of the phonographas, for example, the starting and stopping of the mandrel rotation. This means may be in the form of a switch 43, such as is illustrated in Fig. 1, for controlling the operation of the clutch actuating mechanism l4.

The mechanism l4, schematically shown in Fig. '7, may comprise stop" and "startf electromagnets 44 and 45; an arm 46 pivoted at 46', coupled to the clutch lever III as by the link I3 (see Figure 4), and carrying an armature 41 attractable alternately by the electrom-agnets upon their respective actuations for operating the clutch 8; and means for open-circuiting the electromagnet in actuation and for preparing the circuit of the other electrogagnet for actuation, incidental to the movement of the armature as causedby such actuated electromagnet. These open-circuiting means may comprise the switch contacts 48 and 49 connected in series with the respective electromagnets and adapted to be alternately contacted by the arm 46 so that the arm may thus form a switch pole to which may be connected a conductor 50 forming one side of the power supply for the electromagnets. A conductor 5|, forming the other side of the power supply, may be connected to a contact spring 52 comprising the pole member of switch 43. The terminals of the electromagnets 44 and 45, which are at the ends opposite from the contact terminals 48 and 49, are respectively connected, by the conductors 53 and 54, to the contact members 55 and 56 of the switch 43. The pole contact 52 is adapted to touch alternately the contact members 55 and 56, but is biased to normally touch the contact member 55 which is connected with the stop electromagnet 44, the clutch 9 being thereby normally maintained in a disengaged position so that the machine will normally be in a stopped condition.

The switch 43 may be housed within a rectangular casing 51 projecting from the handpiece 42; a cover 58 for this casing may be pivoted thereto, biased outwardly as by the pole member 52 and movable inwardly so as to move the pole member' 52 into contact with the contact member 56, thereby actuating the start" electromagnet 45 and engaging the clutch 9. Provided the motor M is running, the inward movement of the switch cover 58 will then cause rotational movement of the record R and longitudinal movement relative to the record of the carriage I'I, these movements being however stopped upon the release of the switch cover 58.

During periods of non-use of the phonograph the handpiece 42 may be supported by a hookshaped member 59 projecting forwardly from the left end portion of the base plate I and pivotally connected thereto as by a cross pin 60. When the member 59 is not supporting the handpiece 42, it may be resiliently maintained, as by suitable biasing means, in an upwardly inclined or non-supporting position. Associated with the member 59 is a switch 6| which is serially included in the conductor 50 as shown in Fig. 7.

This switch is adapted to be closed when the member 59 is in a non-supporting position, but is rendered open to shut off the power to the machine when the member 59 is moved down-.-'

it is in other than a condition for recording, I

there have been provided various signalling means as heretofore noted, which signalling means is commonly in the form of a sound signal or of an aptly located light signal. Although sound signals have been used extensively in the past, various forms of light signals are in many cases preferable. For this reason I have chosen to illustrate my invention in connection with a light signal, but it will be understood that my invention is equally applicable to other forms of signalling means.

Where light signals have been employed, the recording condition has been in some cases positively indicated, as by a steady light, and in other cases negatively indicated, as by the extinguishing of the light, the inoperative and reproducing conditions being suitably indicated by differentiations in the operation of the light. In any case however the light operation has been controlled by a relatively complicated circuit arrangement in which the power supplying circuit for the light includes at least a plurality of control devices-such for example as switches. This complication has arisen by reason of the dual function which the control means for the signal light is in general to perform; that is, to differentiate the operation of the light with respect to the various conditions of the machine while the machine is in operation, and to render the light inoperative when the operation of the machine is stopped, irrespective of the condition of the machine .at the time such stopping is effected. For this reason the signal light control means have comprised at least two distinct control devices, one of which is operated incidental to the adjustment of the translating device, and

the other of which is operated incidental to the starting and stopping of the machine-e. g., to the control of the driving means for the mandrel.

I have devised a relatively simple means for controlling the operation of a signal for phono-' graphs. This means for controlling the phonograph signalwhich signal may appropriately be a neon light 62 located on the handpiece 42-is highly dependable and positive in its operation and comprises but a single switch 63. For the illustration of my invention I prefer to indicate the inoperative and reproducing adjustments of the translating device, while the machine is in operation, by afiashing of the light 62. I preferably indicate the recording adjustment of the translating device in a negative manner, such as by the extinguishing of the light, in order that the light may not be bothersome to the operator during recording when the handpiece is held betore his mouth, the light 62 then being directly before his eyes. The indication of other than a recording adjustment by the flashing of the light serves to positively'warn the operator, as he brings the handpiece before his mouth, against dictating into the machine while it is improperly conditioned for recording. It will of course be understood that the particular manner of signalling the operator is not necessarily a limitation of my invention.

Reference being had to Fig. 1 there will be seen the light 62 housed in a casing 64 integrally formed with the handpiece 42. This casing is located in the upper, forward portion of the handpiece and is provided with an opening 64' through which the light may be seen. As seen in Fig. '7, one terminal of the light is connected by a conductor 66 to the pole member 52 of the switch 43,-this member being connected to one side of the power supply by the conductor 5| as hereinbefore described. The other terminal of the light 62 is connected to one of the terminals of the switch 63 by a conductor 61 (which forms with the aforementioned conductors 5|, 63 and 64 a cable 68 that extends along and within the speaking tube ll The other of the switch terminals 66 is connected by a conductor 61 tothe other side of the power supply. Thus the switch 63 is the only control device in the circuit of the light 62 for controlling the operation of the light.

The switch 63 may be of an inertia type, and more specifically of a so-called mercury type, 'which is both statically and dynamically controlled for its suitable operation. A mercury type of switch may comprise a sealed tubular container 69 of suitable insulation material such as glass, a pair of adjacent. contacts 10 extending into one end of the container and forming externally thereof the terminals 66, and a ball of mercury or an inertia element II in the container, as shown in Fig. 3. The tubular container 69 may be disposed in a metal casing I2 and suitably held therein, as by sealing wax 13 inserted into each end of the casing, so that the container may be protected from possible breakage. At one end of the casing 12 there is provided an opening into which is inserted an insulation bead 66' and through which pass the leads connecting the'terminals 66 with the contacts 10; along the side of the casing 12 there is secured, as by welding, a short and relatively wide arm 14 affording easy means by which the casing 12 may be attached to a suitable support.

It will be evident thatthe switch 63 may be rendered open or closed according to the angular position in which it is statically maintained, one such position for rendering the switch open being illustrated in Fig. 3. When the switch is open, as because of such angular positioning of the switch, may be momentarily closed by imparting to the switch, as it appears in Fig. 3, a momentary positive acceleration in a rightward direction, or a momentary negative acceleration (deceleration) in a leftward direction. Consequently, it will be seen that the switch 63 will be intermittently closed as it is placed in a dynamic condition, or moved back and forthin a predetermined path, as by'some suitable reciprocating means. It is also seen that the switch 63 will be open at all static positions of the switch in its predetermined path as long as a suitable angular positioning of the switch is maintained.

Since the switch 63 isv serially included in the circuit of the light 62 thelight will be "extinguished while the switch is open, and flashed while the switch is intermittently closed. Thus in order to extinguish the light 62 while the machine is in a recording condition, I need only statically support the switch in-a suitable open position, as shown in Fig. 3, such static supporting of the switch also serving to positively extinguish the light while the machine is out of operation. Furthermore, in order to flash the light while the machine is in operation and the translating device is adjusted into inoperative and reproducing positions, I need only impart intermittent accelerating movement thereto, for intermittently closing the switch.

It will be seen that an inertia type of switch as herein shown provides a very flexible control for a phonograph signal, since the switch may be supported in a predetermined angular position, to render it either open or closed, and may then further be reciprocated from such predetermined position to cause the switch to be alternately opened and closed. It will be further seen that by such operation of the switch, various forms of signals, such for example as sound or light signals, may be suitably controlled.

The means for operating the switch 83, or for statically supporting the switch in a suitable angular position during some conditions of the phonograph and for vibrating the switch during other conditions of the phonograph, comprise a bracket secured to the upper part of the leftward standard 3 and extending rightwardly therefrom. Along the forward edge of the bracket an arm 16 is bent downwardly, the lower end portion 18' of the arm being inclined rearwardly, as shown in Fig. 2. To this portion 16' a rearwardly and downwardly extending arm 18 is pivotally connected, as by a shoulder screw 19, so that it may swing laterally. The rear end portion of the arm 18 is connected to the arm 1.4 of the switch casing 12, by the screws 80, and is suitably bent so that the switch will be supported in an angular position for rendering the switch normally open. Intermediately of the arm 18 on its left side, there is provided a turned-up ear 8| having an open slot 82. Passing through the slot 82 and threading into the right side of the standard 3 is a headed screw 83 which is provided with a locking nut 84 by which the screw may be: locked into any adjusted or threaded position. Provided on the screw 83 between the head thereof and the ear 8| is a suitable washer 85 preferably made of felt. By the contact of the ear 8| with the washer 85 the rightward swinging movement of the arm 18 is limited, this limiting being deter mined by the adjustment of the screw 83. The arm 18 is biased rightwardly against the washer 85 by means of a tension spring 88 connected between the forward portion of the arm and a turned over arm H at the right end of the bracket I5, the arm 11 being suitably formed and extended rearwardly to serve as a guard for the gear wheel 32.

Provided on the left side of the gear wheel 32 is a disk member 81 having four arcuately shaped cam-actuating arms 81' disposed at equal angular distances about the disk member. The arms 81' are each bent leitwardly, as shown in Fig. 1. Secured to the middle' portion of the arm I8 is a cam 88 which may suitably be made of a Bakelite material. The cam 88 is extended rightwardly and provided with a medium bevel on its forward face 88' and with a relatively steep bevel on its rearward face 88". When the phonograph is in operation, the gear wheel 32 rotates in a counterclockwise direction, as is seen in Fig.

2. Such rotation of the gear wheel 32 causes the actuating arms 81' of the disk member 81 stopped by the contact of the ear 8| with the washer 85, the ball of mercury comprising the inertia element ll of the switch 88 moves onwardly to momentarily short the contacts 1.8. The ball of mercury ll is then moved, as by gravity, away from the contacts I3 to open the switch, the ball of mercury 1| thus acting as a biasing means for the switch; this action may occur as the arm I8 is moved leftwardly at a relatively slow speed by the next following arm 81' of the disk member 81. This cycle of operation is repeated, as each of the arms 18' engage the cam 88, to cause the switch to be intermittently closed and the light 82 to be thereby flashed. Such flashing is adapted to occur while the machine is in operation with the translating device adjusted into either an inoperative or .reproducing position. Due to the relatively high impedance of neon lights, I preferably place a suitable resistor 83, say of 75,000 ohms, in parallel with the light so that the light may not be operated by an extraneous conductances which may appear in the power supplying circuit for the light.

In order that the flashing of the light 62 will not occur while the machine is in operation with the translating device adjusted into a recording r position, the arm 18 is adapted to be moved leftwardly into a position wherein the cam 88 is free of the cam actuating arms 81. In order that the arm '18 may be moved into such leftward position, the front carriage rod I5 is splined to the U-shaped member 28, as by a screw 88 threaded into the member 28 and engaging a longitudinal slot 90 provided in the rod I5; a pin-9| is provided at the left end of th rod l5; and the forward portion of the switch supporting arm 18 is extended leftwardly and then upwardly to form an arm 92 that projects in front of the rod |5 at the place where the pin 9| is located. By reason of the rod I5 being splined to the member 28, the rod is turned in a counterclockwise direction, as seen in Fig. 2, When the control lever 28 is moved upwardly from a neutral" position into a reproducing" position, and into a clockwise direction when the control lever 28 is moved downwardly from neutral" position into "ream-ding position. The pin 9| is free of the arm 92 while the control lever 26 is in either a neutral or reproducing position, but the pin 8| is adapted to contact the arm 92 and thereby swing the arm 18 leftwardly, when the control lever 28 is moved into a recording position. Thus the switch 83 is statically maintained in a position rendering the switch open to cause the light 82 to be extinguished while the machine is in operation and the translating device is adjusted for recording, it being obvious that the switch is maintained in such static condition while the machine is out of operation irrespective of the rotary position of the cam; whereas the switch is suitably reciprocated to cause it to be intermittently closed, and the light 62 to be thereby flashed, while the machine is in operation and the translating device is in either an inoperative or reproducing adjustment.

In Figs. 5 and 6 I saw a modified form of my invention which diners from the former in respect of the form of the cam actuating means, the shape of the cam 33, and the angular position of the switch 93. Whereas in my first embodiment, the switch 93 is inclined at a suitable angle, say an angle 0, with respect to the horizontal, the switch is now inclined at an angle of 1800) from the horizontal, as may be seen by a comparison of Figs. 1 and 2 with Figs. 5 and 6, this being done by bending the switch supporting arm 13 in a direction opposite from that in which it was bent in the former embodiment, the arm I3 being in other respects in the same form. In place of the disk member 81 there are now provided six leftwardly extending pins 93 in the gear wheel 32, the pins being equally angularly spaced about the gear wheel and having their ends slightly beveled. A cam 94, which may be made of Bakelite and secured to the arm 13 as was the cam 93, is provided with a forward face 94' of varying bevel through-' out its length so as to be parabolic in shape, and with a rearward face 99" of substantially fixed but relatively steep bevel.

The operation of this modified form of my invention is as follows: As the phonograph is put into operation, the gear wheel 32 is rotated in a counterclockwise direction as shown in Fig. 6. As one of the pins 93 engages the cam 94, contacting first the rearward face 94'', the switch 93 is moved leftwardly with relatively high acceleration; as the pin 93 thus slides over the crest of the cam 9| the switch is rapidly brought to rest so that the ball of mercury II is thrown, as by its inertia, towards the left end of the switch wherein the contacts are located, the switch then being shorted; as the pin 93 then rides over the forward face 94' of the cam the switch 33 is moved rightwardly with constant acceleration, by reason of the parabolic shape of the cam face 99'. The cam face 94' is arranged so that this constant acceleration of the switch is sumcient to retain the ball of mercury H in the left end of the switch 33 about the contacts I9 against the force of gravity which urges the mercury into the right or lower end of the switch. As the pin 93 rides oil? of the face 94', the switch is held stationary for a moment before the next successive pin 93 contacts the rearward face 93", during which time the ball of mercury 1| is moved by gravity into the right end of the switch to render it open. As the next successive pin 93 contacts the rearward cam face 94", this cycle of operations is repeated.

In this modified form of my invention it will be seen that the ratio of the lengthof the forward cam face 94' to the arcuate distance between the successive pins 93 determines the ratio of the time in which the light 32 is on to the time in which it is "of!" or extinguished. For this reason the length of the cam face 94' is made substantially greater than half the arcuate distance between the successive pins 93, and therefore the light is on during a major portion of the time while the light is being flashed. Such operation of the light affords a very positive warning to the operator.

It will be understood that I use the term "acceleration in the specification and claims, when not qualified, in the broad sense of denoting any change in velocity.

Although I have described and illustrated my invention in certain preferred embodiments, it will be understood that other embodiments, as well as changes in the embodiments herein shown, may be employed without departing from the scope of my invention, which I undertake to express according to the following claims.

In a phonograph having a signalling device: the combination of a translating device and means associated therewith for adjusting it into recording and other conditions; a switch for controlling said signalling device having open and closed conditions and including relatively movable inertia means causing the switch to be shifted between the said conditions in response to a bodily reciprocation of the switch and to be maintained in one of its said conditions when the reciprocation thereof is stopped; movable switch supporting means; switch reciprocating means including a cam device operated during the operation of the machine and a cam follower carried by said supporting means; means biasing said cam follower into operative relationship with said cam device; and means, operatively associated with said adjusting means and controlled in predetermined relation to the adjustment of the translating device, for moving said cam follower out of operative relationship with said cam device.

- 10. In a phonograph having signalling means: the combination of a translating device and means associated therewith for adjusting it into recording and other conditions; a movably mounted switch for controlling said signalling means having open and closed conditions; relatively movable inertia means associated with said switch and causing the switch to bev shifted between its said conditions in response to a bodily reciprocation of the switch and to be maintained ditions throughout said portion; and means controlled by said adjusting means for placing said cam follower into and out of operative association with said cam device.
